So, I am sorta a "new guy" (was a lurker for years) and the main reason that I decided to buy the book was because it was relatively inexpensive and because I tend to like to support industrious folks. Think of this as a "kickstarter" book. For the most part, I followed the thread that was the genesis of this book and I got the general gestalt of the diet from that. I still wanted to support these guys.
I just finished the book. First off, I find it hilarious to read multiple pages in Gal-speak. All of the strange abbreviations ("ppl", not "people"), missing spaces between words, lack of punctuation, all just like the posts here. Honestly, an editor would ruin the book for me. It's almost reached a GH15-like level of linguistic finger-printing.
Anyway, the diet itself is actually pretty simple and could be explained in a couple of pages, but these guys took it a step further and talked about gear, supps, training, willpower methods, mental state. It's actually pretty good. With an editor, it could be a well-thought out 200 page book.
The thing is that I doubt that I have the mental toughness to pull this off (plus, my wife would probably kill me, she is only barely tolerant of my nutritional quirks as it is), but much of what I try to do has whispers of this diet plan in it: it draws some of the insulin-sensitivity "science" from the intermittent fasting guys and the macro ratios are pretty well used in other research. It comes down to willpower.
The chapters on gear were the most interesting, because as a natty, I know really nothing about that side of the "sport" (oh, brother) and was interested in Gal's very simple approach. Ofc (another Gal-ism for "of course"), he is a sample size of one. But his recommendations of extreme moderation are fairly comforting for a guy who is well into the TRT/HRT years.
All in all, I am happy with the purchase. I have spend a LOT more on a lot less over the years and I am happy to help a couple brothers out.
Good job.
